My invention relates to centrifugal apparatus for separating purposes and particularly to centrifugal apparatus for se'p arating solid particles suspended in a liquid.

6 The object of my invention is to pro-- vide a centrifugal apparatus to separate in a continuous operation solid particles'suspended in liquids, whether said sol-id particles are of more specific gravity than the 1 liquid, whether they are of. less specific gravity than the liquid or whet-her they are of the same specific gravity as the liquid.

Another object of my invention is to provide a centrifugal apparatus for separating 1 purposes of very simple construction, which has no screw conveyor inside of.the container nor any moving mechanism inside of the rotating container, therefore elim-. -inating' all, the disadvantages foundjn separators of that kind.

being separated, by any movingparts operating inside of the rotating container; this is very objectionable in the separation of sugar, salt and other materials which are produced in a'crystal form. r a It will be noticed that instead of which are pressed against the walls of the container by the centrifugal action,- and dragging them along thewalls ofsaid container in order to remove them from the place where they were settled'by the centrifugal force, I 'reverse'the centrifugal'action on the spot where said solids are settled, by which means the said solids are pushed away and out from \the same walls on which they were lying*- the same centrifu a1 force which presses the solids against t e walls on one side. ofthe container, removes the same solids on the other side of the container. The reversing of the centrifugal.

act-ion in the container is accoin lished-by e5 rotating said container 'around ahaxis placed eccentrically to its ownaxis of retatiOm, i 4

For an illustrationof several ofthe man i forms my invention, may take, reference is to be had to the accompanying drawings inwhich I W I Fig. 1 is a longitudinalusectional view,

partly in elevation, of an apparatus embody-. ing .my invention, and having. two con-- A further ob 'ect of my invention is to avoid the grindlng of the solids which are remov-. ingby any mechanical means the solids of reversing the centrifugal action, which is-the spirit of this invention, as will be hereafter described and claimed.

Fig. 4 is a right front view of the appa-' ratus'shown in Fig. 3.

Fig.5 is a sectional view of one of the rotary bowls of-the apparatus at the center and at right angle to its axis, which shows another arrangement for the liquid openings which also will be described hereinafter.

Fig. 6 is a sectionalview of a container showing the direction of the lines of force, to which the discharging solids and liquids are subjected. These lines of force are very important, in order to clearly understand the principle 'of my invention.

Fig. 7 is a sectional'view of, a container showing the position ofthe screens in the container :and the directionv of the lines'of force of the liquid as it leaves the container. In the process of separating suspended solids ,in liquids by means of centrifugal force, a bowl or chamber which contains the mixture isrotated at a suitable speed,

usually the-solids, being-of greater specific gravity, are pressed by' centrifugal action v against-the wall at the periphery of the periphery of the container. In other words,

in a rotating bowl'which rotates on a central axis, the centrifugal force tends to press the'solids all around the peri hery of said container or bowl and can on y be directly removed by some other force which acts independently from the centrifugal force.

In the apparatus embodying my inven-' side of the wall at the periphery of the con-' tion, the centrifugal force presses the solid particles only against one part on the inner lo'w shaft 2 which may form an integral.

art of member 1, as shown in the drawing.-

11 the rotating member 1, and eccentrically to its axis aremounted the shafts 3, firmly secured to member 1, by nuts 4, and having extensions ,5, which form the axis on which bowls 6 are mounted and made to rotate by means of a gear 7 which is mounted on shaft 9, and 'acts on the-gears 8, which form an integral part of the bowls 6. It will be apparent thatthe bowls 6 will rotate around the axis 5 in proportion to the difierential of speed at which shaft 2 and shaft 9 will rotate. If the speed at which shaft 9 rotates is greater than the speed at which shaft 2 rotates and the rotation of shafts 9' and 2 is inthedirection shown by the arrows 40, shown in Fig.2, the direction at which the bowls 6 will rotate is shown by the arrows 41 shown in Fig. 2. Another extension 10, provides the means for securing firmly the receivers 11 to the extension 5 of. the shaft 3, so that said receivers 11 will always be in the same position in regard to the member 1, and to the axis on which said member 1 rotates. The seats on said receivers 11 firmly secured by nuts 12, prevent the bowls 6 from coming outfromthe axis 5 and keeps them in position.

Mounted inside of bowls 6 and forming an integral part thereto, a suitable number of vanes 13 are set at a convenient angle, so as to form pockets which will carry the solid particles from outer end of the bowls to the inner endof .the same, when the bowls move around their own axis 5 by means of shaft 9 and gear 7.

A member 15 is mounted to the extensions 14 which form an integral part of the rotating member 1, and firmly secured thereto by means of nuts '42 clearly shown in Fig. 4. Said'member 15 has a small chamber 16 to receive the liquid which is to be treated, said liquid being supplied by pipe 18. Extending from chamber 1.6 there are pipes 17. one for each bowl, which object is to convey the liquid from chamber 16- to the inside of the bowls 6 discharging the liquid at 1.9, shown in Figs. 2 and 4. The member 15 is mounted 'the lines of force 50 and 50 menses in such a manner so as not to interfere with the rotation of the bowls 6 on their axis 5. It is apparent that the liquid which gets into chamber 16 will be thrown by centrifugal force away from the axis of rotation of said chamber 16, which axis is the same as that of the rotating member 1, and will be forced through the pipes 17 and finally discharged into the bowls 6 and at a point 19, shown in dotted lines in Figs. 2. and 4.

The receivers 11 which are secured on shaft by means of nuts. 12 and bolts 20 can be adjusted to any desired position. in order to properly receive the solid particles at the proper place around the periphery of the bowls 6- and to switch themoutside of the bowls 6 where they can be received by any suitable means In Fig. 6 I show a container working under the same principle as the one shown. in

Fig. 5, with the only .difference that the screens 43 which are mounted on the vanes 13 are more clearly shown, and that in this figure I also show the lines of centrifugal force 50. These lines 50 will greatly help to understand my invention. -They show the direction followed by the liquids and solids when leaving the pockets formed by the vanes, at any position in which said vanes happen to be in regard to the external axisof rotation, about which the container rotates. This direction will always be radial inregard to the external axis of rotation. as shown at 44, but will vary in regard to the container according to the position of the vanes in regard to the lines of force. at the time the liquids or solids are discharged from the vanes. It will be clearly understood that the solids can be discharged .into the receiver 11 only between the lines of force 50 and 50 as shown at 54.

It is apparent that in order to carry the solids away from the liquid zone between points 64 and 65 and empty them into the receiver 11,. the vanes 13 have to be set at an angle in regard to the radius of the con tainer, having its center at the internal axis of rotation 62, and toward the direction of rotation of said container about its own axis, toform pockets as shown by the vane 45, the wall of the periphery 47 and an arc line 46 which center is the external axis 61. Said arc line 46 cuts the point of contact of the tangential line of force 50 and the periph-- cry of the container at 66,.and also makes contact with the end of the vanes at 66. The solids can only be thrown into the receiver 11 by the vanes 13 when said vanes pass the arc line 46 and get into the zone between It is apparent that if the vanes 13 are set in a radial position about the internal axis 62, there will not be any solids left in the pockets by the time the vanes 13 reach the point 60, because they would have been thrown out by container.

m mas the action of the centrifugal force in the di-' rection of the lines of force shown at 44. It is also obvious that the receiver can not be extended outside of the lines of force 50 5 and 50 because it will be in the ,wayof rotation of the vanesv 13 about the internal axis 62; therefore solids must be emptied by the pockets into the receiver '11 during the time the vanes 13 move. from point 66 to point 67 in rotation about the internal axis 62;

In Fig. 7 I show a container which works under the same principle as the one shown in Fig. 3 and Fig. 4 with the only difference that it shows the direction followed by the a liquid when leaving the container, which direction is the same as the lines of force 53, and also shows in a clearer waythe screen 43 on the vanes whichform the'pockets, and the screen 51 forming the periphery of the The operation of the apparatus is as follows :The apparatus may be mounted on any suitable bearing not shown, may be operated in any desired. position, vertical, horizontal, or at any angle. The hollow shaft 2 .1s made to rotate by any suitable means, and at any convenient speed. At the same time shaft 2 mounted inside of the hollow shaft 2 is also made to rotate, it may rotate faster or slower than the shaft 2 but in case it rotates' slower the bowls5 will rotate in the opposite direction and the position of the pockets and vanes should be reversed.- It is obvious that any differential of speed between shaft 9 and shaft 2'will cause the gear forced to follow through the 7 to rotate to one direction or another in relation to member 1, on which bowls 6 are mounted; therefore the bowls 6 will also rotate on their own axes 5 by means of gear 7 Lacting on gears 8 which form an integral part of the bowls 6. It is apparent that the rotation of the bowls 6 on axis 5 will be accomplished regardless of the speed at which member 1 will rotate, as long as there is a differential of speed between shaft 2 and shaft 9.

While the whole apparatus is in action, the

I liquid to be treated is supplied by pipe 18 and discharged inside of chamber 16. Due

to the centrifugal force'produced by the rotation of the apparatus the liquid will be ipes 17 and finally will be poured inside 0 the bowls 6. By the centrifugal action of the rotating member 1 on which the bowls 6 are mounted the liquid will only be stored on one side of the bowls as shown at 22. The same centrifugal action will cause the solids to be pressed against the outer side of the wall at the periphery of bowls 6 where vanes 13 forming a pocket will catch said solids andv convey them around to the opposite side, when the centrifugal action on the wall is reversed, and instead of pressing the solids against the wall, they will be pushed away from said wall and into the receivers 11 vanes 13 and together with the solids will gradually overflow from said pockets as they will filter through conducts provided in the vanes as shown in Fig. 5 at point 27 and only the dry solids will be carried around to be poured on the receivers 11 and out of the apparatus. The liquid, free from solids, may be overflowcd over the edge at 23 shown in Fig. 1 or may be forced through conducts 24 on the wall'forming the periphery of the same as shown in Figs. 3 and 4. -The angle of the position of the receivers 11 may be changed at will to suit conditions.

While the apparatus can be constructed with a pluralityof bowls 6' placed around the member 1, it can also be constructed with only one bowl as is shown in Fig. 3 but in this case it is advisable to place a weight not shown on the arm 30 at the opposite side of the location of the bowl 6 so as to balance the apparatus and avoid vibrations in the machine. Another object of letting the liquid fiIter out through the walls of the bowls as shown at 24 in Figs. 3 and 4, instead of letting the liquid overflow as shown at '23 in Fig. 1, is to enable the apparatus to of member 15 instead of'being mounted on the shaft 5 as shown In Fig. 1.
